Docker is an open-source platform that automates the deployment of applications inside lightweight, portable containers. These containers package applications with their dependencies, ensuring consistent behavior across different environments.

Key Concepts 📌

  • Containers: Lightweight, standalone packages containing code, runtime, system tools, and libraries.
    docker_container
  • Images: Templates used to create containers. Think of them as read-only blueprints.
    docker_image
  • Docker Hub: A cloud-based repository for sharing container images.
    docker_hub

Use Cases 🚀

  • Development: Streamline workflows with isolated environments.
  • Deployment: Ensure applications run reliably in production.
  • Scaling: Easily scale applications across servers or clouds.

Why Docker? ✅

  • Consistency: "Write once, run anywhere" for application environments.
  • Efficiency: Faster deployment and resource utilization compared to virtual machines.
  • Portability: Containers can run on any system with Docker installed.
